I have some newby questions about dns.
Here are the steps that lead me to those :
C:\Windows\system32>nslookup google.ca Serveur : p81-004.pixelweb.net Address: 22.214.171.124 Réponse ne faisant pas autorité : Nom : google.ca Addresses: 2607:f8b0:4006:80b::1018 126.96.36.199 188.8.131.52 184.108.40.206 220.127.116.11 18.104.22.168 22.214.171.124 126.96.36.199 188.8.131.52 184.108.40.206 220.127.116.11 18.104.22.168 22.214.171.124 126.96.36.199 188.8.131.52 184.108.40.206
C:\Windows\system32>nslookup 220.127.116.11 Serveur : p81-004.pixelweb.net Address: 18.104.22.168 Nom : cache.google.com Address: 22.214.171.124
Note that I got
cache.google.com for any of those addresses.
- My questions are :
- why is that an entire range of ip addresses are associated with only one host name
cache.google.com, is it related to ssl?
- why did
nslookupomitted some google addresses within the range 207:251 that respond perfectly in my browser?
- why is that
https://126.96.36.199is resolved whereas
- why firefox tells me that
https://188.8.131.52isn't certified connection, while
Thanks a lot for your answers!
